Definitions
- the invention relates to a microporous adsorbent which is suitable for adsorptive material separation.
- Adsorptive material separations have hitherto been carried out, for example, using granular microporous adsorbents which, owing to their microporous structure, have a high effective surface area and thus adsorption capacity. It was also known to add these microporous granular adsorbents with reactive textile dyes
- the invention has set itself the task
- microporous adsorbent its inner and outer surfaces are coated with an adsorbable layer in the highest possible thickness and density, with only short diffusion paths being present in the matrix, in order to thereby also ensure the highest possible adsorption of the substances to be separated.
- microporous adsorbent according to the invention which is characterized by a
- Membrane filter the outer and inner surfaces of which are provided with a grafted-on layer of a hydroxyl-containing polymer modified with a reactive textile dye.
- a grafted-on layer of a hydroxyl-containing polymer modified with a reactive textile dye In contrast to the previously used, in particular
- Adsorbenses invention the adsorbable
- the diffusion paths are also much shorter than in the case of the granular microporous materials previously used, so that on the one hand due to the high availability of the adsorbable material on the inner and outer surfaces of the Membrane filter base material and the given short diffusion paths, the adsorbent according to the invention has significantly higher adsorption capacities than the previously known materials.
- Microporous polymer membranes can be divided into ultra and microfiltration membranes, the former being characterized by the pore sizes that they are used for
- membrane filters and their manufacture are known. They can be made from any natural or synthetic materials, preferably natural or synthetic polymers, especially synthetic ones
- Membrane filters preferably made of nitrogen-containing polymers, in particular of aliphatic or aromatic polyamides, polysulfonamides, polyurethanes or polymers, which contain the nitrogen not in the main chain but in the
- German patent office have been described), that is, by reacting the hydroxyl-containing starting monomers with the membrane filter from a
- Halogenating agent hydrogen atoms on the nitrogen Atoms of the polymer membranes are replaced by halogen atoms and some of them are removed by reducing agents in the presence of ethylenically unsaturated monomers with radical grafting onto the nitrogen atoms and then the remaining halogen atoms are replaced by reducing agents in the absence of
- the grafted-on hydroxyl-containing polymers can then be modified in a known manner with reactive textile dyes which are chemically fixed to the grafted-on polymers.
- cibachron blue F3GA is used as the textile dye, but all textile dyes previously used for such adoptions are suitable, in particular for the
- Cibachron blue has a specific binding capacity for
- Enzymes especially for dehydrogenases, are also suitable, albumin from the other plasma proteins
- Hydroxyethyl methacrylate is preferably used as the hydroxyl group-like monomer, but there are
- the absorption capacities in the adsorbents according to the invention are considerably higher than those of the known granular microporous adsorbents or similar known materials.
- the polymer layer grafted on according to the invention is a water-swellable gel, in the
- Base material fleece-reinforced nylon membrane filter with a nominal pore size of 0.45 ⁇ m.
- Thickness 215 ⁇ m
- Proportion of the graft polymer (based on nylon matrix + graft polymer): 31.7% by weight
- microporous adsorbents according to the invention are expediently used in a device as described in DE-OS 39 29 643.1 (patent application filed on the same day as the present application under the internal
- Adsorbents compared to the known, in particular granular adsorbents, for example based on agarose, consists in that when the material dries out no damage, such as a drastic decrease in the
- Binding capacity to be feared Binding capacity to be feared.
- temperatures up to 110 ° C can be used without problems. However, there is a certain drop in temperature at higher temperatures
- Binding capacity Surprisingly, it was found that impregnation of the material with an aqueous 2-40% glycerol solution, preferably a 5-20% and particularly preferably a 10% solution, not only that
- Waste of the binding capacity is practically completely avoided, but also the shelf life is significantly improved.
- glycerin other substances used in the technology to prevent complete dehydration, e.g. Sorbitol or ethylene glycol can be used, but glycerin is generally preferred.
- Glycerol content of the adsorbent according to the invention also significantly improved its light resistance. This is of great practical importance insofar as the photosensitivity of textile dyes is generally known and, without special precautions, such as the glycerol impregnation mentioned, the material is already stored under the influence of
- Nylon 6.6 membranes with a nominal pore size of 0.45 ⁇ were used as the base membranes for the fixation of Reactive Blue 2 (trade name: Cibacron blue F2GA, Ciba-Geigy), according to the method described in the application P 39 29 647.4-44
- the dye ligand was fixed on one
- Material web is alternately wound up and unwound.
- the back and forth web of material is constantly pulled through the tub and thus with a fresh treatment solution in
- a freshly prepared aqueous solution of 5% cibacron blue F2GA, 10% urea, 0.3% Ludigol (BASF) and 2.18% sodium hydroxide was used as the dye liquor.
- the temperature was kept at 23 ° C and the treatment was carried out over a period of 20 hours.
- the dye liquor was then drained from the jigger and the membrane web, also in the
- a 25 mm diameter membrane sample was placed in a filtration device and a solution of 250 ⁇ g / ml LDH in 10 mM
- Fig. 1 are the binding capacity and the
- Pore size range is about 20% is required to ensure high binding capacity, the increase in binding capacity from a decrease in
- Example 1 A starting membrane with a degree of grafting of 28%, which otherwise corresponded to the starting membranes mentioned in Example 1, was also used in Example 1
- Dye 10% urea, 2.5% sodium hydrogen carbonate and 2.5% sodium carbonate.
- Polyethylene bags were glued to a south-facing window.
